| Polymer polyols are polyethers based on general polyether polyols, which are polymerized by adding acrylonitrile, styrene and other vinyl monomers and initiators. Mainly used in soft bubble field. Polyether polyols are mainly made of propylene oxide as raw materials, and are grafted to sucrose, glycerol, diethylene glycol and other polyols, which are mainly used in soft bubbles, hard bubbles, adhesives and so on | ||||||||
